Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a rotating mounting bracket for a photovoltaic power station. Background Technology

[0002] Photovoltaic technology is an important component of the renewable energy sector, and with the increasing global demand for clean energy, photovoltaic power generation systems have developed rapidly. One of the core components of a photovoltaic power plant is the photovoltaic module, whose main function is to convert sunlight into electrical energy. To maximize the energy absorption efficiency of photovoltaic modules, the installation method is crucial.

[0003] Most traditional photovoltaic (PV) power plants use a fixed-angle installation method, meaning the PV modules are fixed at a specific angle and cannot be adjusted according to changes in the sun's position. This fixed-angle installation method means that the PV modules cannot receive sunlight at the optimal angle during certain periods, especially in the morning and evening or in different seasons, when the sun's altitude and azimuth angles change. Fixed-angle PV modules struggle to capture the optimal angle of sunlight, resulting in low energy absorption efficiency.

[0004] Different regions have different latitudes and climate conditions, and fixed-angle photovoltaic modules are difficult to adapt to these differences. Especially in high-latitude regions, the solar altitude angle differs significantly between summer and winter, and fixed-angle modules cannot make full use of year-round solar resources. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a rotating mounting bracket for photovoltaic power stations, which solves the problem of low energy absorption efficiency caused by the fixed-angle installation of photovoltaic power stations in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0007] A rotating mounting bracket for a photovoltaic power station includes a rotating device, an angle adjustment device mounted on the rotating device, and a photovoltaic module mounted on the angle adjustment device. The back of the photovoltaic module is provided with a first hinged lug and a second hinged lug. The first hinged lug is hinged to a fixed plate arranged horizontally, and the second hinged lug is hinged to the angle adjustment device. The angle adjustment device can drive the photovoltaic module to rotate along the first hinged lug.

[0008] To achieve the above technical solution, the photovoltaic module is hinged to the fixed plate and the angle adjustment device via a first hinged lug and a second hinged lug, respectively. The second hinged lug is connected to the angle adjustment device, and as the angle adjustment device moves, the photovoltaic module rotates around the axis of the first hinged lug. The rotation device can drive the angle adjustment device and the photovoltaic module to rotate within a certain range. Through the coordinated work of the angle adjustment device and the rotation device, the photovoltaic module can achieve dual adjustment of elevation and azimuth angles. The photovoltaic module can dynamically adjust its angle according to the sun's trajectory to maximize the illuminated area and improve energy absorption efficiency. The photovoltaic module can adapt to the sun's trajectory in different geographical locations and seasonal changes, improving the versatility and adaptability of the equipment.

[0009] In one embodiment of the present invention, the rotating device includes a base, a worm gear rotatably disposed on the base, a turntable disposed on the worm gear and used to place the fixed plate, and a driving assembly for driving the worm gear to rotate.

[0010] To achieve the above technical solution, the base serves as the basic support structure of the entire bracket, used to support all other components. The worm gear is mounted on the base to achieve horizontal rotation. The turntable is mounted on the worm gear to hold the fixing plate and drive the components to drive the worm gear to rotate, thereby adjusting the horizontal angle of the photovoltaic modules and thus adjusting the angle of the modules relative to the sun.

[0011] In one embodiment of the present invention, the angle adjustment device includes a connecting plate hinged to the second hinge ear plate, and an adjustment component hinged to the other end of the connecting plate and capable of driving the connecting plate closer to or further away from the first hinge ear plate.

[0012] To achieve the above technical solution, the connecting plate is hinged to the second hinge ear plate, and the adjustment component is hinged to the other end of the connecting plate, which can drive the connecting plate to move closer to or away from the first hinge ear plate, thereby realizing the adjustment of the photovoltaic module angle.

[0013] In one embodiment of the present invention, the adjusting assembly includes a lead screw, fixing blocks disposed at both ends of the lead screw, a nut sleeved on the lead screw and hinged to the connecting plate, and an adjusting motor disposed at one end of the lead screw and driving the nut to move along the lead screw.

[0014] To achieve the above technical solution, when the regulating motor is working, it drives the lead screw to rotate. Depending on the direction of rotation of the regulating motor, the lead screw will cause the nut to move along its length. Since the nut is hinged to the connecting plate, the movement of the nut will cause the connecting plate to rotate around the first hinge lug, thereby adjusting the angle of the photovoltaic module.

[0015] In one embodiment of the present invention, the drive assembly includes a worm gear meshing with the worm wheel and a drive motor disposed at one end of the worm gear.

[0016] To achieve the above technical solution, when the drive motor is working, it transmits power to the worm through the shaft. When the worm meshes with the worm wheel, the spiral teeth of the worm push the tooth surface of the worm wheel, causing the worm wheel to rotate. Through the precise control of the worm wheel and worm gear mechanism, the photovoltaic module can more effectively follow the movement of the sun, thereby improving the solar energy collection efficiency and power generation. The self-locking performance of the worm wheel and worm gear mechanism can prevent the photovoltaic module from changing position due to external forces, thus improving the stability of the structure.

[0017] In one embodiment of the present invention, the worm gear is provided with a housing located at the lower end of the turntable.

[0018] To achieve the above technical solution, the outer casing of the worm gear provides physical protection, preventing the intrusion of dust, moisture, and other external factors that may affect the normal operation of the worm gear. At the same time, due to the protection of the casing, the maintenance requirements of the worm gear and worm are reduced, decreasing damage and maintenance costs caused by external factors.

[0019] As described above, the rotating mounting bracket for a photovoltaic power station of this invention has the following beneficial effects: By dynamically adjusting the angle of the photovoltaic modules, it ensures that the photovoltaic modules are always facing the sun, maximizing the illuminated area and improving energy absorption efficiency. Dynamic angle adjustment ensures that the photovoltaic modules receive optimal sunlight conditions at different times of the day; the automated angle adjustment and rotation device reduces the need for manual intervention, lowering operating costs; the bracket design allows the photovoltaic modules to adapt to different geographical locations and seasonal solar trajectories, improving versatility and adaptability; and through efficient energy absorption, it reduces the need for large areas of land, optimizing land use efficiency. Especially under conditions of limited land resources, dynamic adjustment can maximize energy output per unit area. Attached Figure Description

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features can be combined with each other.

[0025] Please see Figures 1 to 2 This utility model provides a rotating mounting bracket for a photovoltaic power station, including a rotating device, an angle adjustment device disposed on the rotating device, and a photovoltaic module 1 disposed on the angle adjustment device. The back of the photovoltaic module 1 is provided with a first hinge ear plate 2 and a second hinge ear plate 3. The first hinge ear plate is hinged to a fixed plate 4 arranged horizontally, and the second hinge ear plate 3 is hinged to the angle adjustment device. The angle adjustment device can drive the photovoltaic module 1 to rotate along the first hinge ear plate 2.

[0026] The photovoltaic module 1 is hinged to the fixed plate 4 and the angle adjustment device via a first hinged lug 2 and a second hinged lug 3, respectively. The second hinged lug 3 is connected to the angle adjustment device, and as the angle adjustment device moves, the photovoltaic module 1 rotates around the axis of the first hinged lug 2. The rotation device can drive the angle adjustment device and the photovoltaic module 1 to rotate within a certain range. Through the coordinated work of the angle adjustment device and the rotation device, the photovoltaic module 1 can achieve dual adjustment of elevation and azimuth angles. The photovoltaic module 1 can dynamically adjust its angle according to the sun's trajectory to maximize the illuminated area and improve energy absorption efficiency. The photovoltaic module 1 can adapt to the sun's trajectory in different geographical locations and seasonal changes, improving the versatility and adaptability of the equipment.

[0027] The rotating device includes a base 5, a worm gear 6 rotatably mounted on the base 5, a turntable 7 mounted on the worm gear 6 for placing the fixed plate 4, and a drive assembly for driving the worm gear 6 to rotate. The base 5 serves as the basic support structure for the entire bracket, bearing all other components. The worm gear 6 rotatably mounted on the base 5 enables horizontal rotation. The turntable 7, mounted on the worm gear 6, holds the fixed plate 4. The drive assembly drives the worm gear 6 to rotate, thereby adjusting the horizontal angle of the photovoltaic module 1 and thus adjusting the angle of the module relative to the sun.

[0028] The angle adjustment device includes a connecting plate 8 hinged to the second hinge ear plate 3, and an adjustment component hinged to the other end of the connecting plate 8 and capable of driving the connecting plate 8 closer to or further away from the first hinge ear plate 2. The connecting plate 8 is hinged to the second hinge ear plate 3, and the adjustment component is hinged to the other end of the connecting plate 8, enabling the connecting plate 8 to move closer to or further away from the first hinge ear plate 2, thereby achieving angle adjustment of the photovoltaic module 1.

[0029] The adjustment assembly includes a lead screw 9, fixing blocks 10 at both ends of the lead screw 9, a nut 11 sleeved on the lead screw 9 and hinged to the connecting plate 8, and an adjustment motor 12 located at one end of the lead screw 9 and driving the nut 11 to move along the lead screw 9. When the adjustment motor 12 is working, it drives the lead screw 9 to rotate. According to the rotation direction of the adjustment motor 12, the lead screw 9 will cause the nut 11 to move along its length. Since the nut 11 is hinged to the connecting plate 8, the movement of the nut 11 will cause the connecting plate 8 to rotate around the first hinge lug 2, thereby adjusting the angle of the photovoltaic module 1.

[0030] The drive assembly includes a worm 13 meshing with the worm gear 6 and a drive motor 14 disposed at one end of the worm 13. When the drive motor 14 operates, it transmits power to the worm 13 via a shaft. When the worm 13 meshes with the worm gear 6, the helical teeth of the worm 13 push the tooth surface of the worm gear 6, causing the worm gear 6 to rotate. Through the precise control of the worm gear 6 and worm 13 mechanism, the photovoltaic module 1 can more effectively follow the movement of the sun, thereby improving the solar energy collection efficiency and power generation. The self-locking performance of the worm gear 6 and worm 13 mechanism can prevent the photovoltaic module 1 from changing position due to external forces, thus improving the stability of the structure.

[0031] The worm gear 6 is externally provided with a housing 15 located at the lower end of the turntable 7. The outer housing 15 of the worm gear 6 provides physical protection for the worm gear 6, preventing the intrusion of dust, moisture, and other external factors that may affect the normal operation of the worm gear 6. At the same time, due to the protection of the housing 15, the maintenance requirements of the worm gear 6 and worm 13 are reduced, reducing damage and maintenance costs caused by external factors.

[0032] This application also includes an angle measuring instrument and a control system. The angle measuring instrument is installed on the photovoltaic module 1 or at a key part of the bracket to detect the current angle of the photovoltaic module 1 in real time. The angle measuring instrument can be a photoelectric encoder, gyroscope, or other high-precision angle sensor. The control system controls the operation of the adjusting motor 12 and the drive motor 14 based on the detected angle information and preset solar trajectory data to adjust the elevation and azimuth angles of the photovoltaic module 1. By introducing the angle measuring instrument and the control system, the rotating mounting bracket of the photovoltaic power station can achieve intelligent automatic tracking and angle adjustment, significantly improving the energy absorption efficiency and power generation of the photovoltaic module 1, adapting to solar trajectories with different geographical locations and seasonal changes, and improving the versatility and adaptability of the equipment. The above embodiments are only illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
